SPRING-SUPPORT FOR MOTOR-CYCLE AND OTHER SADDLES.

Specification of Letters Patent.

Patented Jan. 23, 1912.

Application filed April 26, 1910. Serial No. 557,674.

To all whom itma'y concern:

Be it known that I, FREDERICK ROBINSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring-Supports for Motor-Cycle and other Saddles, of which the following is a specification.

The invention relates to means for suspending or supporting a saddle for motor cycles or analogous vehicles with the result of more perfectly absorbing vertical and horizontal shocks than in constructions heretofore used or proposed.

The invention comprises two double-leaf longitudinal springs from and by which the seat is suspendedand directed in its movements; also other features of improvement; all of which are hereinafter set forth.

In order to make the invention more clearly imderstood I have shown in the accompanying drawings means for carrying the same into practical effect, without limiting my improvements, in their useful applications, to the particular construction which, for the sake of example, I have delineated.

In said drawingsFigure 1 is a perspective view of a motor cycle saddle having supporting means embodying the invention. Fig. 2 is a vertical sectional View of the upper part of the seat post. Fig. 3 is a plan view of the latter. Fig. 4 is a plan View of the end of the spring A. Fig. 5 is a side view of the spring which holds the check plate disengageably against the spring B. Fig. 6 isa sectional view of the spring shown in Fig. 4. Fig. 7 is a plan view ofthe rear end of the spring B showing the check plate and spring in section.

Referring to the drawings, 1 indicates the seat post, and 2 the saddle, the latter being indicated in dotted lines for the sake of clearness of the other parts.

The seat post may terminate in a downward extension 3 adapted to be inserted into a vertical or inclined socket in the motor frame, or may terminate in a horizontal extension 4, shown in dotted lines, adapted to fit into a horizontal socket or bar of such frame.

B is the lower element of the double leaf spring formed with a, curved portion 5 which fits in a corresponding socket 6 in the post 1, so as to admit of forward and backward adjustment to give the seat the desired tilt longitudinally. and vertically.

T and U indicate clamping wedges which may be inserted into the socket 6, above the spring B, through an opening 7. Between these Wedges is an expanding wedge V into which screws a bolt X. By the latter the clamping wedges may be forced forward and backward to securely hold the spring B in its adjusted positio By preference I combine with the spring B and on top of the same a taper leaf spring member 8.

A is the upper element of the double leaf spring arranged above the element B and extending rearwardly to near the end of the saddle. It may have on its under side a reinforcing tapering spring leaf 12. At the front end it is united with the spring B by a bolt E which passes through a washer N below the lower spring, through elongated holes 9 in the springs, and screws into a nut 0 above the upper spring. The ends of the springs are preferably curved as shown and the inner faces of the washer and nut are correspondingly curved, thus giving an even bearing in all compressed positions of the springs. The bolt E is used to vary the combined tension of the two elements of the double spring A B so as to suit riders of different weights with equal comfort.

M is a clamp bolt passing transversely between the springs A and B, holding them apart and acting as a fulcrum for the action of the rear end of the spring A. This bolt passes through perforations in the end flanges of a clasp L which rests on the spring A and embraces and holds in line the springs A and B. The upper partof the clasp L is provided with a tubular bearing 10 in which is pivotally held a rocker O, the lower ends of which are united by a transverse bolt 11. I

The parts A and B, combinedas described, form a V-shaped spring from which the saddle may be conveniently suspended, and which is perfectly adjustable as to tenslon.

F is a U-shaped leaf spring which supports the front end ofthe saddle It is formed with a tubular pivotal bearing 13 which fits around the bolt 11, and the upper end of the spring is united by clamps 14 with the front ends of the saddle stretcher, rods G and pommel 15. The rear ends of the stretcher rods are secured by bolts 16 with the cantle 17 The rear end of the saddle is carried by coiled springs H, I, the upper ends of which are secured by the bolts 16. The lower ends of these coiled springs rest on pivot blocks J, K, and are held thereto by bolts 18. The blocks J, K are formed with transverse tubular bearings 19 which embrace the pivot ends 20 of the rear rocker D. This rocker is united by nuts 21 with a U-shaped journal 22 which is embraced by bearing 23 formed at the rear end of the spring A.

P is a check plate which prevents the springs A and B from springing too far apart when the saddle is relieved of the riders weight. This check plate is formed at its upper end with a tubular bearing 24 which embraces a transverse clamp bolt S. The latter passes through the ears of a clasp R which rests on the spring A and is clamped thereto by the said bolt S. The lower end of the check plate passes down against, or through a slot 27 in the rear end of the spring B and is formed with a lip or hook 25 which engages under such spring to limit the upward movement of the check plate. The clasp R is adjustable longitudinally on the spring B so as to cause the check plate to point downward, or cliagonally downward, when the springs A, B, are compressed, without striking any portion of the cycle frame. The check plate is held in the slot in which it moves by a V- shaped spring 26 which is placed between the under side of the spring A and the back of the check plate. While limiting the separation of the springs A and B, the check plate also keeps the springs in line one above the other and prevents a sidewise displacement of the spring A when the saddle is accidentally struck on the side.

The position of the fulcrum, and of the front rocker C, may be varied by adjusting the clasp L forward or backward on the springs as may be required.

In the saddle support above described, there is great freedom of motion to meet vertical and also horizontal shocks,

I the saddle very'easy riding. The front and rear rockers may swing forward or backward together or independently as may be required, giving the saddle an easy floating support.

It will be seen that the adjustment of the clamp and fulcrum bolt M varies the tension of each member of the double leaf spring at the same time, and affects the tension of the spring as a whole.
